TamSil 290


TamSil 290 is a water-based, silane-siloxane system which penetrates deeply into porous substrates to allow for a bonded hydrophobic lining to the pores. This treatment significantly reduces the absorption of water and waterborne salts but still allows the passage of water vapour. The solution does not produce any discolouration of the substrate and has excellent resistance to weathering.
